[NTG-context] latest beta and file mismatch problem

I have just installed the latest beta (minimals) and updated my .bash_profile (as advised) so that it now reads: . /Applications/ConTeXtMinimals/tex/setuptex /Applications/ConTeXtMinimals/tex/texmf-osx-64/bin When I try to compile any file, I get: FatalError : Your format does not match the base files! FormatVersion : 2009.11.26 16:28 MKII FilesVersion : 2009.12.01 00:14 How do I fix this? (texexec --make --all did not do the trick.) Alan
